Pay only for what you use. There are no set-up fees or upfront commitments to begin using Amazon CloudSearch. The major portion of a typical domain’s costs come from search instance usage. All source documents and updates to the domain are stored behind-the-scenes on Amazon S3 for data durability and recovery, but customers get this for free, which is a significant cost saving over self-managed search infrastructure. Estimate your monthly bill using the AWS Simple Monthly Calculator.

Customers are billed according to their monthly usage across the following dimensions:

Except as otherwise noted, our prices are exclusive of applicable taxes and duties, including VAT and applicable sales tax. For customers with a Japanese billing address, use of the Asia Pacific (Tokyo) Region is subject to Japanese Consumption Tax. Learn more.

Pricing is per instance-hour consumed for each search instance, from the time the instance is launched until it is terminated. Each partial instance-hour consumed is billed as a full hour.

When you enable the Multi-AZ option for enhanced data durability and availability, Amazon CloudSearch provisions and maintains additional search instances in a different Availability Zone. Search traffic is distributed across all of the instances and the instances in either zone are capable of handling the full load in the event of a service disruption. When you enable the Multi-AZ option, you are charged for the additional search instance hours used at the regular rates for the applicable region.

Below are the prices for previous generation instances, which are only available for existing search domains. All newly created domains will be provisioned with the higher performance newer generation instance options.

When you make configuration changes to your index, for example by adding a field, you will need to rebuild the index. To do this, you use the AWS Management Console, command line tools, AWS SDKs, or APIs to issue an IndexDocuments request. The charge for this request is:

$0.98 per GB of data stored in your search domain

Amazon CloudSearch may occasionally issue these calls for you. For example, as you add data to your domain, Amazon CloudSearch may proactively rebuild your index to improve query performance. You will not be charged in this case, and others, where you do not explicitly call IndexDocuments.

The pricing below is based on data transferred "in" and "out" of Amazon CloudSearch.
